Abstract:
This study investigated the correlation and predictive capacity of verbal working memory (VWM) to the reading comprehension of children in their first language (L1) and second language (L2). The term verbal working memory refers to a cognitive system with a limited capacity that can hold and manipulate verbal and auditory information temporarily. A sub-aim was to investigate the contribution of L2 linguistic knowledge in L2 reading comprehension. Sixty-three Grade 3 South African children completed a reading comprehension test and VWM assessment (forward span, backward span, and sentence repetition tasks). L2 participants completed a receptive language assessment to delineate whether their linguistic knowledge (L2 vocabulary and grammar knowledge) would be more predictive of L2 reading comprehension in comparison with VWM. Regression and correlation analyses revealed that VWM is not predictive of L1 or L2 reading comprehension. L2 linguistic knowledge, however, significantly correlates with L2 comprehension and VWM capacity, although it is not a significant predictor of L2 reading comprehension. Our findings suggest that reading in an L2 is a multidimensional skill in which no single isolated variable can account for good versus poor reading comprehension.
